What Is a Number Line?
A number line is a visual representation of numbers that is usually represented as a straight line. The numbers are usually represented as points on the line, and the distance between each number corresponds to the difference in value between them. In an elementary school setting, you can use a number line to introduce basic mathematical concepts and to help students develop their number sense. They can be used for a wide variety of different activities such as counting, comparing numbers, and more.How Do Number Lines Help Students?
This tool has a number of applications in helping build numbers skills, some of which may surprise you! Take a look at the ways these can help your elementary students:- They aid learning by providing a visual representation of numbers and their relative positions.
- They make it easier for students to understand concepts such as addition, subtraction, and fractions, as well as to visualize and compare numbers.
- They can be used to introduce negative numbers and to understand the concept of absolute value.
- They can help students develop their number sense (aka the ability to understand and work with numbers in a flexible and efficient way).
Creative Ways to Use Number Lines
Looking for fresh ways to use number lines? Explore our collection for printable activities and ideas, and explore this list of favorites from our teacher team!- Number Line Scavenger Hunt: Students can search for specific numbers on the number line and write them down. They can also be given a range of numbers to find and write down the numbers that fall within that range.
- Number Line Word Problems: Students can use a number line to help them solve word problems involving addition, subtraction, or fractions. They can use the number line to visualize the problem and find the solution.
- Number Line Drawings: Students can draw a scene that uses a number line, such as an ocean that shows the depth below sea level. Or perhaps they decide to integrate a number line into a drawing that has a thermometer to show positive and negative temperatures.
- Number Line Sidewalk Art: Students can draw horizontal and vertical number lines with side-walk chalk. They can get up and move between numbers showing how to represent addition, subtraction, rounding, and more.
- Number Lines with Clothespins: Students can sequence clothespins marked with integers, fractions, or decimals. . This helps with fine motor concepts for younger students, while older students can be challenged to match equivalent value clothespins on their number line. (Such as equivalent fractions, decimals, and percentages)
- Number Line Riddles: Give students a riddle they can solve with the use of a number line!
